* **Improvements**
+ * Adapt to musl-1.2.4
+
+ The latest version of musl stop declaring some symbols that libvirt's test
+ suite used (for redirecting ``stat()`` family of functions), leaving the
+ tests broken. This is now fixed and the test suite works even with the
+ latest version of musl.
+
+ * conf: Introduce ``<address/>`` for virtio-mem and virtio-pmem
+
+ To ensure guest ABI stability, libvirt persists address for memory devices,
+ now including ``virtio-mem`` and ``virtio-pmem``. The address can be also
+ specified by user.
+
* **Bug fixes**
+ * qemu: Account for NVMe disks when calculating memlock limit on hotplug
+
+ When no ``<hard_limit/>`` is set, libvirt still tries to guess a sensible
+ limit for memlock for domains. But this limit was not calculated properly
+ on a hotplug of ``<disk type='nvme'/>``.
+
+ * numa: Deny other memory modes than ``restrictive``` if a memnode is ``restrictive``
+
+ Due to a missing check it was possible to define a domain with incorrect
+ ``<numatune/>``. For instance it was possible to have a ``<memnode
+ mode="restrictive"/>`` and ``<memory/>`` of a different mode. This
is now
+ forbidden and if either all ``<memnode/>``-s and ``<memory/>`` have to
have
+ ``restrictive`` mode, or none.
+
+ * qemu: Start emulator thread with more generous ``cpuset.mems``
+
+ To ensure memory is allocated only from configured NUMA nodes, libvirt sets
+ up cpuset CGgroup controller, even before QEMU is executed. But this may
+ prevent QEMU from setting affinity of threads that allocate memory. Since
+ these threads are spawned from the emulator thread, the initial set up must
+ be more generous and include union of all host NUMA nodes that are allowed
+ in the domain definition. Once QEMU has allocated all its memory, the
+ emulator thread is restricted further, as it otherwise would be.
